Download iOS 4 Firmware for iPhone and iPod Touch

Apple has released the iOS 4 firmware for iPhone 3GS, iPhone 3G and iPod Touch 3G and 2G along with SDK 4. On Moday, June 7th Apple renamed iPhone OS 4 to iOS 4. iOS 4 firmware Build 8A293 is now available to developers enrolled in the iPhone Dev Program masses. iOS 4 Final will be released to masses in a couple of weeks.

iOS 4iOS 4 brings a lot of new features for both developers and users as well. The iOS 4 firmware is build 8A293 and iOS 4 SDK is build 10M2262. iOS 4 is not available to general public. However if you still want to give it a shot and download iOS 4, read the warning below and scroll down to find download links.

WARNING: Jailbreakers and iPhone unlocker MUST stay away from iOS 4 until the dev-team or someone releases new jailbreak and unlock tools for iOS firmware. iOS 4 requires iTunes 9.2. Updates will be posted at the bottom.

NOTE: iOS 4 fully supports iPhone 3GS and iPod Touch 3G but in iPhone 3G and iPod Touch 2G some features like multitasking won’t work (+1 reason to jailbreak).

iOS4 in your device now?

Do you have a developer account?
Or is that the method described in the article does not require a developer account??

I downloaded and installed with out having a sdk license BUT

it appears that multitasking soesnt work properly i can access items in said multitask area but they really are not running pandora will stop playing and games restart anyone have any ideas.

PS i used windows 7 64 bit and worked as far as installing is concerned flawlessly!

iPhoneHeat June 18, 2010, 4:59 pm

first, it’s GM.. may have some bugs

download the firmware you want on your computer and save it in a place where youll remember and make sure you remember the file name (itll end in .ipsw),next put your ipod (or iphone) in dfu mode(look up on youtube) connect it to itunes it’ll ask you to restore hold down shift and select the restore button browse for your downloaded .ipsw select it and there you go! enjoy and comment back (if needed follow this website
itll show you pretty much everything

iPhoneHeat July 11, 2010, 5:37 pm

it’s not a zip that you extracted.. it’s a direct link to IPSW..
use Firefox chrome or IE to download it
safari often extracts IPSW
